x Mangave plant named ‘My Dog Spot’

ABSTRACT

A new and unique cultivar of X Mangave plant named ‘My Dog Spot’ characterized by compact, low-growing habit and lanceolate foliage with medium green color and with high ultra violet light exposure developing burgundy speckling on light green to chartreuse leaves. The yellowish to chartreuse flowers on tall stiff scapes are loaded with nectar for attracting hummingbirds. The new plant is suitable as a patio or container plant, for the garden or for use as a houseplant.

Botanical classification: x Mangave times x Mangave hybrid.

Variety denomination: ‘My Dog Spot’.

STATEMENT REGARDING PRIOR DISCLOSURES UNDER 37 CFR 1.77(b)(6)

The first public disclosure of the claimed plant, in the form of a photograph and brief description on a website operated by Walters Gardens, Inc. on Feb. 1, 2018. The claimed plant was first sold on Mar. 12, 2018 by Walters Gardens, Inc., who obtained the plant and all information relating thereto, from the inventor. No plants of x Mangave ‘My Dog Spot’ have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior to the filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct X Mangave plant, X Mangave ‘My Dog Spot’ hybridized on Apr. 17, 2014 by the inventor at a wholesale perennial nursery in Zeeland, Mich., USA as a cross between an unreleased proprietary hybrid known by the breeder code H10-02 as the female or seed parent and an unreleased proprietary hybrid known by the breeder code 12-06-01 as the male or pollen parent. Through trials at the same nursery the plant was referred to by the code 14-18-2. The new plant has been successfully asexually propagated initially in 2016 by division at the same nursery in Zeeland, Mich. and also by tissue culture. Both methods of asexual propagation systems have been found to produce stable and identical plants that maintain all the unique characteristics of the original plant in successive generations.

BRIEF SUMMARY OF THE INVENTION

X Mangave ‘My Dog Spot’ differs from its parents as well as all other Manfreda, Agave and X Mangave known to the applicant. The most similar known X Mangave cultivar known to the inventor are: ‘Spotty Dotty’ U.S. Plant Pat. No. 29,917, ‘Inkblot’ U.S. Plant Pat. No. 29,431, ‘Freckles and Speckles’ U.S. Plant Pat. No. 30,904, and ‘Bloodspot’ (not patented).

‘Spotty Dotty’ is a larger plant and has significantly broader, greater number and more green leaves with smaller spots of purple, blushing in high light intensity and a slightly more wavy leaf. ‘Inkblot’ has leaves that are broader and arch more, with larger spots and a more greyed-purple coloration to the leaf and the flowers are burgundy colored and not the yellowish flowers of ‘My Dog Spot’. ‘Freckles and Speckles’ is larger in habit with broader, more ovate-shaped and thicker leaves, the leaf color is more greyed-purple and the flowers are darker with more burnt-orange hue blushing on the tepals. ‘Bloodspot’ is more upright in habit with more leaves per plant that are more ovate-shaped the terminal and marginal spines are larger and darker reddish colored. The female parent has bright yellow flowers on heavier branched scapes and the foliage is more silvery, broader and more wavy than the new plant. The male parent has flatter habit, a non-branched scape with mahogany flowers, the foliage is more silver with fewer but larger burgundy spots, and foliage is broader than the new plant.

The new plant, ‘My Dog Spot’, is unique from all of these variegated Agave, X Mangave and Manfreda known to the inventor by the following combined traits:

-   -   1. Compact, low-growing habit with 30 to 45 leaves at flowering;     -   2. Foliage lanceolate with small flexible marginal teeth;     -   3. Foliage develops burgundy speckling throughout on light green         to chartreuse leaves;     -   4. Moderate to rapid growth rate with good natural pup         production;     -   5. Yellowish to chartreuse flowers on stiff, upright,         non-branched scapes.

BRIEF DESCRIPTION OF THE DRAWINGS

The photograph of the new plant demonstrates the overall appearance of the new plant including the unique traits as a three-year-old plant grown in a container in a greenhouse with supplemental water and fertilizer as needed. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, temperature, source and direction may cause the appearance of minor variation in color.
